A space for simulation related technical resources and discussions.
Sometimes, it is necessary to add mass to a model to reduce complexity, change the center of gravity, or update load cases. Radioss tracks two types of masses: Structural and Non-Structural. Structural mass is determined by the size of the element and material density. Non-structural mass is determined by the user and can…
This article gives more information regarding the concept of ports and sources in CADFEKO. What is a port in CADFEKO To cause current to flow in a model, you need to excite or illuminate a model. A port is a mathematical representation of where energy can enter (source) or leave a model (sink). Define a port where you want…
Abstract In this article we will use a novel AI-based application, romAITM, to generate a Reduced-Order-Model (ROM) from a large database of static simulations and optimize their parameters. We will demonstrate how this innovative approach can support the design of an Aircraft Wing. The romAI model will be used to estimate…
An efficient workflow to follow when dealing with complex and/or dirty CAD models with numerous solid parts and numerous small details is as follows: 1) Delete all unnecessary parts 2) Delete any Bolts&Logos using the Geometry>Cleanup>Defeature tool 3) Make sure there are no big gaps/holes in the model. For this we usually…
You need powerful tools for motor drive design, simulation, and analysis. Altair provides them. We achieve the fastest and most accurate simulations on the market that will make your work more efficient than ever. Key challenges that engineers often face in motor drives include: * Motor performance evaluation * Controller…
Since 2016 PSIM has supported a link with SPICE, but what does this mean? What you can do. The simple explanation is that you can decide to use a spice engine to run a simulation that has been built using the PSIM schematic editor, but there is no co-simulation between the PSIM engine and SPICE. Here is a tutorial video to…
When building a CAE model, there are a lot of information you should input in order to successfully run your analysis and of course, to have reasonable results. In this article we will show a couple of tools and features we have available within HyperWorks and OptiStruct to validate your model and avoid error messages and…
Use case The plane strain formulation assumes that the strains in the plane perpendicular to the axis (or simply out-of-plane) are zero or irrelevant. When running a CAE analysis, using the plane strain assumption can lead to considerable savings in computational time and file storage. The simplification to a 2D mesh also…
Altair commitments As a starter, some of the modifications changed the way we write the inp file. Our choices for the format of the inp file are driven by development decisions, considering not only Abaqus, but also the consistency and the ease of conversion with other solvers supported in HyperMesh. As Abaqus supports…
As we introduced several significant changes for Abaqus in 2022, the article below isolates form the general release notes the improvments that are related to Abaqus. 2022.3 Significant changes: Enhancements * Sub-Categories for Load Collectors in Abaqus Interface Load collectors are now organized into sub-categories in…
